IDEA StatiCa Steel

IDEA StatiCa Steel is used by engineers dealing with members, joints, connections, details and cross-sections

of steel structures. Its functionality is organized into modules depending on the member which is to be analyzed

and designed - Connection, Beam, Column, Frame etc.

We have created a unique method for structural analysis and design of connections called component-based finite

element model (CBFEM). Engineers can work with joints, connections and footing without limitation in shapes

and loading. Templates for most-used connections are available. Choose from frequently-used or general cross-

sections and wide range of hot rolled and sheet welded members. IDEA Connection, with CBFEM method

in its core, is:

Changing steel joint and connection design

IDEA Connection and CBFEM method are results of our long-term R&D efforts in the area of structural design

and check of steel structure joints. In 2013, after years of preparations, we teamed up with top Czech universities

and after 2 years of intensive development, testing and verifying a new tool for steel engineers was born.

IDEA Connection with CBFEM provides precise checks, results of strength, stiffness and buckling analysis of steel

joint. Bolts, welds, concrete blocks are checked according to common design formulas.

IDEA CSS, Beam, Column, Frame

This package of modules gives our customers powerfull tool for complete design of steel members.

It provides comprehensive ULS/ SLS code checks and strength, buckling and fire resistance design

according to Eurocode EN 1993-1-1 with National Annexes. Unique FEA calculation of cross-section

properties and stress distribution is available.

Component Based Finite Element Model of steel joints

Engineers typically design steel connections that follow prescribed building code requirements based on lab empirical testing,

computational model verification and engineering judgment. However, many projects have situations where the connection

design must be validated using engineering judgment or even perform a more comprehensive connection analysis.

These practices have several challenges:

First, when designing non-typical connection designs not explicitly covered by the building codes, the engineer may not have

the experience to just use engineering judgment unless they use time-intensive, computational modeling and simulation methods.

Second, creating such computational models to study and validate connection behavior can consume a lot of time on projects,

impacting profitability.

Third, the reliability of steel connection designs can vary from project to project. In fact, when deviations happen in fabrication

and erection, the actual connection behavior may perform quite differently than anticipated.

Therefore, engineers are looking for a more accurate, project-specific way of studying connection behavior to better understand

their connection designs, while doing so productively.

IDEA Connection with CBFEM inside is: GENERAL SIMPLE AND FAST COMPREHENSIBLE

• Joint is divided into components

• All steel plates are modeled by Finite Element method assuming ideal elastic-plastic material

• Bolts, welds, concrete blocks are modelled as nonlinear springs

• FE Model is used for investigating of internal forces in each component

• Plates are checked for limit plastic strain – 5% acc. to EC3

• Each component is checked according to specific formulas as in Component Method

R&D project IDEA Connection

Research and development team for this project was formed by core employees of IDEA RS (Lubomír Šabatka & team) and

academic staff from two Czech universities FCE CTU Prague (prof. František Wald & team) and FCE VUT Brno

(prof. Miroslav Bajer & team). We put together long-term experience with development of component method (CM), practical

experience with design of steel structures and proven professional experience with FEM and SW development.

We started in 2013 with a question:

“Can we analyze steel joints in a more precise and general way?”

We know the answer today:

“YES, we can!”

Key features of IDEA Connection

• Joints with various numbers of beams in multiple directions and loads

• Analysis model created according to manufacturing operations used – cuts, plates, stiffeners, ribs, openings,

cleats, welds, bolts etc.

• Automatic generation of joint’s FE model, user does not handle with FEA

• Stiffness analysis of any kind of connection

• Efficient FEA solver delivers result faster than current methods

• More than 90% of calculations is national-code independent

• Calculation of internal stress/forces in joints based on elastic/plastic FE analysis

• Clear information about behavior of the joint/connection

• Local buckling analysis of steel joint, critical load factor

The goal was to develop a method and tools for analysis and check of steel joints of general shapes and loadings.

New CBFEM method is:

GENERALso that it is useable for most of joints,

anchors, and details used in building

practice

SIMPLE AND FASTso that it provides results in time

comparable with currently existing

methods and tools

COMPREHENSIBLEso that structural engineer gets clear

information about joint behavior,

stress, strain and reserves of individual

components and about overall safety

and reliability

Geometry of joint, manufacturing operations

Input or joint geometry is a very easy process. Of course rolled, welded or cold formed cross-sections are supported. Model of

a joint is created by operations according to real-life manufacturing what makes modeling intuitive. All steel plates have precise

shapes which can be used for drawings or in CAD/CAM.

Joint templates

• Wide range of predefined joint/connection templates enables fast work with typical connections

• Any joint designed in IDEA Connection can be saved „as template“

• Any template can be reused for joint of similar topology.

are designed properly in 3D model of the structure.

Only local effects in joints are investigated.

• Thin plates in pressure like webs, flanges,

ribs etc. can cause the collapse of steel joint.

• CBFEM calculates stability on the same model

as for stress/strain analysis.

• Critical buckling shapes and buckling factors are provided.

• Engineer can find weak parts of the joint and decide about

appropriate measures.

Impact for daily work of engineers

Motto of our company is Calculate yesterday’s estimates – we try to create something new, something that solves issue

engineer have. IDEA StatiCa Steel is a perfect example of this. We researched a new CBFEM method which can design steel

joint of arbitrary topology and loaded in all directions. We put this functionality in a product with a powerful computing and

graphic engine while keeping it simple. We want IDEA StatiCa Steel to be a tool for wide engineering public, not just a couple

of academics. We kept the calculation time comparable to currently used (and simplified) methods because IDEA Connection

creates CBFEM model automatically.

Our users report that they can get results of sophisticated connection tasks in 20 seconds.
